Wanted - Innovation Rockabilly E string.

[andyonbass]

I've only gone and lost the E string from my Rockabilly set, either the missus has had a tidy up or more likely I think it may have been left in the pocket of an old gig bag that had I had to bin a little while ago . I fancied putting them back on today and can't find the bloody thing anywhere.
Long shot I know, but does anybody have a spare to sell, or know where I could buy one singularly? Its one of the black ones so would look a bit odd if I left the existing E on, even if it sounded ok
Thanks in anticipation
Andy
